Will we ever travel through time?

Question

I remember the old tv show of the 1960s 'The Time Tunnel" about two guys getting lost through time after an experimental miscalculation of a goverment projected time tunnel. of course we got the H.G. Wells novel "The Time Machine" made twice into the movies. Now, these are science fiction. Do you suppose someday humans will be able to travel through time and meet Napoleon, hope not to meet Attila the Hun...quite an unfriendly guy he was, or go to the mysterious future and see what will happen to our descendants? What do you think folks?

Answer 1

From what we know about time - it will never happen.

One question that is relevant here is whether time travel is permitted by the prevailing laws of nature. This is presumably a matter of empirical science (or perhaps the correct philosophical interpretation of our best theories from the empirical sciences). But a further question, and one that falls squarely under the heading of philosophy, is whether time travel is permitted by the laws of logic and metaphysics. For it has been argued that various absurdities follow from the supposition that time travel is (logically and metaphysically) possible. Here is an example of such an argument.

(1) If you could travel back in time, then you could kill your grandfather before your father was ever conceived. (For what's to stop you from bringing a gun with you and simply shooting him?)
(2) It's not the case that you could kill your grandfather before your father was ever conceived. (Because if you did, then you would ensure that you never existed, and that is not something that you could ensure.)
(3) You cannot travel back in time.

Another argument that might be raised against the possibility of time travel depends on the claim that Presentism is true. For if Presentism is true, then neither past nor future objects exist. And in that case, it is hard to see how anyone could travel to the past or the future.
Despite the existence of these and other arguments against the possibility of time travel, there may also be problems associated with the claim that time travel is not possible. For one thing, many scientists and philosophers believe that the actual laws of physics are in fact compatible with time travel. And for another thing, as I mentioned at the beginning of this section, we often think about time travel stories; but it is very plausible to think that a story cannot depict things that are downright impossible. For example, it is natural to think that there could not be a story in which two plus two are five, or in which there is a sphere that both is and is not red all over. (This seems especially true if the story is told pictorially, as in the case of a movie.) Hence, if time travel is impossible, then we should not even be able to consider any story in which time travel occurs. And yet we do so all the time! One task facing the philosopher who claims that time travel is impossible, then, is to explain the existence of a huge number of well-known stories that appear to be specifically about time travel.

Answer 2

Time travel might be impossible, per se.
There's an emerging theory today that time
is little more than energy changing.
We can't understand the change, so we make
up this dimension called time.

The "Big Bang" is considered to be a beginning.
Suppose it's just a point in a 63 billion year cycle.

Mass forms when quarks explode and interface
with invisible forces we call laws of physics.
Time and space are merely by-products of this
reaction.
However, the quarks and other bosons have
been there all along, as has been the forces.

In short, if we take a bunch of scrap iron and build
a 1924 Ford, then, for that particular vehicle, it
would be 1924, even though we call this 2007.

I have a pet theory that every boson has an assigned
genetic frequency. If this turns out to be true, many
mysteries will suddenly be solved.

Answer 4

Nope, no way, Time travel to the past isn't possible. Such would be the same as defying the laws of physics. You can attribute that to the grandfather paradox. If you could go back in time and you killed your grandfather before your father/mother was born, you would never be born, but if you were never born, how could you travel back in time?

You could replace anyone in that scenario.

Bottom Line: You can't travel back in time because to do so would change the past, which isn't possible.

As for traveling to the future maybe, if you could build some sort of suspended animation apperatus. But you could never go back.

Answer 5

Nope, if we could travel through time, then time itself would have to be multidimensional. There would have to be a mainstream of time that you were travelling against, as well as a secondary stream of time that you would be travelling IN. If you were outside of time, how could you move, given that time is the fourth dimension?
Also... just a hunch, if time travel were possible, either,

1- we would have people from the future visiting us and records of people from the future visiting people in the past
OR
2- Time travel will be outlawed for fear of altering history

Answer 6

In an Ideal World yes

Answer 7

We are all time travelers, one second at a time.

Answer 8

yeah we will be able to time travel in like 500-1000 years

Answer 9

No; the laws of quantum physics would have to be violated which means we wouldn't exist.

Answer 10

We can only back down a second?
Definitively no.
